Apple's Impersonation Risk Detection in iOS 27 checks for signs of social engineering scams on the device and lets supported apps react to the risk level without sending personal data to Apple.
01Summary
- 01Apple added Impersonation Risk Detection to iOS 27 in September alongside Siri AI.
- 02The feature is designed to help spot scams that try to steal money or account details by posing as banks or government agencies.
- 03It analyses interaction patterns, timing and context on-device and sends only a risk level to the app.
- 04Users can enable it in Settings, then Privacy & Security, then Impersonation Risk Detection, by switching on Share with App Developers.
- 05Apple says changes can take up to 24 hours to take effect, and the feature works only in supported apps.
02Why it matters
This matters because it adds another layer of protection against scams that can get past traditional safeguards like two-factor authentication. It could mean more warnings, delays or identity checks in apps you use.
